What is Mass (liturgy)?

Mass is the main Eucharistic liturgical service in many forms of Western Christianity. The term Mass is commonly used in the Catholic Church, and in the Western Rite Orthodox, and Old Catholic churches. The term is used in some Lutheran churches, as well as in some Anglican churches. The term is also used, on rare occasion, by other Protestant churches.

Other Christian denominations may employ terms such as Divine Service or worship service , rather than the word Mass. For the celebration of the Eucharist in Eastern Christianity, including Eastern Catholic Churches, other terms such as Divine Liturgy, Holy Qurbana, Holy Qurobo and Badarak are typically used instead.
